Application filed November lz, 1913.- Serial No. 800,567.

To all whom it in ay concern:

Be it known that we, EDWARD H. HAZEN,. a citizen of the United States of America,

and resident-oi New York, in the county and State of New York, and ,SAMUEL' L.

LEVI, a citizen of the United States, and resident of New York, in the county and .which, preferably in combination with an auxiliary wedge element or equivalent, will permit of the ready detachability of the calk. and with greaterconvenience and despatch than have been possible heretofore.

Another object is to provide a device as .above described, and one which. in addition to supporting the call: orcalks present in an exceedingly simple manner, will positively prevent the accidental loss or displacement of any or all thereof.

Other objects and aims of the invention. more or less broad than those stated above, together with the advantages inherent."'w1ll be in part obvious and in part specifically referred to in the course of the following description of the elements, combinations. arrangements of parts, and applications of principles constituting the invention; and the scope of protection contemplated will appear from the claims."

In the accompanying drawing, which is 7 :-.to be taken as a part of this specification,

however, being shown asnot yet bent over upon themselves as disclosed in Fig. 1;

Fig. 3 is a transverse sectional view, taken on the line 33 of Fig. 1;

Fig. l is a view similar to Fig. 3, but taken on the line lt of Fig. 1; and

Fig. oillustra tes a slightly different conv closure of an illustrative application of this invention in connection with the provision of an auxiliary overshoe will best secure the objects and advantages herein set forth and apparent. and referring now particularly and l of the drawing. an ordinary horse-shoe is delineated at"6, in

dotted lines in l and in full lines in Figs. 3 and r.

The overshoe structure here provided and adapted for removable attachment to said shoe (3 includes the substantially similar and svmmetrically arranged opposed sidesertions 7. Each section is provided with a.

central horizontally extending and offset extension 9 as shown. each extension terminating in an upturned vertical lip 10. Lips 10 are suitably transversely apertured. and these apertures are provided with right and left threads. respectively, so that with 'sections 7 opposed-as disclosed-in Fig.1 and with the correspondingly threaaed ends of the single screw 11 each cotiperatlng with may be turned in one direction or-the other to draw together or urge apart said sections 7. Screw 11.;carries a nut 12 fixedly thereon. and a nut 13 loosely thereon the former for utilization in turning-:the-screw llandthe" latter for clamping saidascrew'against rotation after it hasbeenpredeterminedly adjusted. P r

Each section 7 carries inka manner now to'be described a plurality of road-engaging' elements. as the calks 14. The shank of each of the calks lt illustratedin Figs. 3 and 4. is shown as including two parallel and vertical walls 15 and 16 (Fig. 3). and two substantially parallel but inclined walls one of said threaded apertures, said scrdw upon said ed to abut respectively 17 and is (Fig. 4. The shank of each of these just mentioned calks 14, together with the transverse'slots illustrated as formed. in

the sections 7. Each transverse slot (as will be seen from Fig. 1) has four side walls, two of these walls (as will be seen from Fig. 3) being oppositely the walls 15 and 16 of a calk shank, and. the other two of these walls (as will be seen from Fig. being oppositely disposed and adapted one to abut the wall 17 of a calk-shank and the other to abut the wedge 19 and thus indirectly bear against the wall 18 of the calk-shank. The dimensions and relations of a slot and its associated calk-shank are such that with the wedge 19 entirely removed from the slot, the free end of the shank is insertible into the slot in the direction of the arrows 20 one disclosed in Fig. 3 and the other disclosed in Fig. 4. During the process of thus inserting the calk-shank, the wall 18 thereof will preferably and usually travel upward in substantial adjacency to the wall of the slot which in Fig. 4 is shown as in abutment with the wedge 19. Immediately thereafter the calk is rocked in the direction of the arrow 21 to bring the wall 17 of the calkshank into abutment with the wall of the slot which is shown in Fig. 4 as-being in abutment with said wall 17. The wedge 19 is then inserted in the direction of the arrows 22 disclosed in Figs. 3 and 4, the design of said wedge being such that when it is so illustrated in Fig. 4 and in an obvious manner, lock the .cal'k against displacement in the direction of the arrows 22 before the sections 7 are mounted upon the shoe 6 and lock the calk against displacement in any direction after the sections 7 are mounted shoe.

The wedge 19 shown in section in Fig. 4 may be located at 19 in Fig. 3, being bounded by the dotted line 23, the full -line 24 and the calk-shank Walls 15 and 16. The dotted line 25 represents theunder surface of a section 7 as well as the joining line between the calk and its shank. It will be seen from Figs. 3 nd 4 that .the wedge is not as long as the ca k-shank; but the lower edge of the wedge, instead of resting on an uninterrupted ledge located within the associated slot, is here supported against accidental displacement in the, direction of the arrow 22 by means of its abutment with a pair of spaced ears 26 (one of which is shown in full lines in Fig. 4 andboth of which are shown in dotted lines in Fig. 3). Cooperating with wall 18 of the calk shank (Fig. 4), said wall being prolonged into a groove 27 (shown in dotted lines in Fig. 3 and in full lines in Fig. 4), the (ITS 26 disposed and adapt-- shoe 6 forced home it will, 218' establish an upwardly extending passage through which may be inserted a wedgeejecting tool of any desired type. This construction renders exceedingly expeditious and convenient the ejection of a wedge 19, especially thereafter force from within the slot the wedge 19. It is quite obvious, on the other hand, that with the wedge 19 properly inand'the sections 7 mounted upon the as hereinafter described, it will be utterly impossible to accidentally eject a wedge 19 and drop'from its slot.

As to the method of mounting sections 7 upon the shoe 6, attention is first called to the upstanding lugs 8 in Fig. 2. The sections. 7 are preferably in practice carried upon the underside of the shoe and the lugs 8 are bent over upon themselves as isclosed in Figs. 1, 3 and 4 so that the vertical portions of the lugs may embrace the outer side edges of the shoe 6 an'dthe horizontal portions of said lugs may engage with the upper face of said shoe, the general relation of the parts being best indicated in Fig. 1.

place,

The lugs 8 may be thusbent upon themselves before or after initially mounting the sections 7 upon the shoe 6, the dimensions of the vertical portions of the lugs in any event preferably being such that the proper grip may be given to any of the ordinary horseshoes of varying thicknesses. The lugs 8 having been so bent, the side sections are drawn together to mount the entirestructure here illustrated upon the horse-shoe 6, in an obvious manner and by a preliminary adjusting manipulation of the nut 12 and afinal and clamping adjustment of the nut 13.

Attention is called tothe disclosure in Figs. 3 and 4 of the substantially continuous bead or tenon 29-carried by a section 7, which, if desired, may be utilized in connection with a cooperating substantially continuous groove or channel 30- carried by a calk 14, the tenon and the groove being adapted in an obvious manner to diminish the torsional stress which would otherwise in practice be at times put upon the calk- 1.

with the sections 7', or afterthey 4 have been dismounted from the shoe 6- thus render a calk 14 free to tion 7 may carry an extension 9 similar to the extension 9 shown in Fig. 1, so that with the lug 8 bent over as shown, any ad- ]usting device associated with the extension 9, such as the screw 11 shown in Fig. 1, may be manipulated either to draw the sections 7 in the direction of the arrow 31, to temporarily lock in place the calk 14, or

.to force the sections 7 inthe direction of the arrow 32 to render the calk 14 and its integral structure instantly removable and, if desired, replaceable by another calk structure of substantially the same type.

It will thus be seen that we have provided an embodiment of this invention well calculated as aforesaid to attain the various ends and objects thereof, and one, moreover, having important advantages of simplicity,-economy, efficiency and ease'of manipulation.

Inasmuch as many changes could be made in the above construction, and many apparently widely different embodiments of our invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying draw- .ing shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the language used in the followlng claims 1s mtended to cover all the generic and specific.

features of the invention'herein described and all statements of the scope, of the nvention which, as a matter of language,

mi ht be said to fall therebetween.

aving descrlbed our invention, what we claim as new and desire to secure by Letters Patent, is:

1. In a combination, a calk-carrying member having an opening extending therethrough, a calk having a shank adapted to be inserted upwardly into said opening, and a wed e )iece adapted to be inserted downwardly lnto said opening between the wall of the opening and the calk shank, said wedge piece having a length not greater than the device of the kind described, in-

distancefrom one side of said opening to the other, and when in wedging relation with the calkshank extending substantially to the outer end of said opening andliot beyond the same, I

2. In a device of the kind described, in combination, a calk-carrying member having an opening extending therethrouglna calk having a shank adapted to be inserted upwardly into said opening, and a wedge piece adapted to be inserted downwardly into said opening between the wallof the opening and the calk shank, said wedge piece having a length not greater than the distance from one side of said opening to into said opening between the wallet the opening and the calk shank, said wedge t 8.

piece having a length not greater than distance from one side of said'opening to the other, and when in wedgin relation with the calk shank extending su stantially to the outer end of said opening and not beyond the same, said calk being cut away to afford access to the outer end of the wedge piece, the portions of the calk about said cut-out portion bearing against the said member beyond said opening.

In witness whereof we have hereunto signed our names in the presence of two witnesses. i EDWARD H. HAZEN.
